The standard introduced several key shifts from traditional rigid-tank methodologies: ACI-350 3-06 Seismic Design of Liquid-Containing
, titled "Seismic Design of Liquid-Containing Concrete Structures and Commentary," is a standard published by the American Concrete Institute (ACI). It was reported by ACI Committee 350 and released in 2006. The document is 67 pages long and is available for purchase as a PDF download through the ACI website.

The standard is versatile enough to be used for a wide range of projects, from large wastewater treatment plants and elevated water towers to more specialized applications like the seismic design of large swimming pools.

Before the introduction of ACI 350.3, the seismic design provisions for liquid-containing concrete structures were, by many accounts, "very limited in scope". The 1989 edition of ACI 350 offered only a general description of fundamental principles, leaving engineers to rely on a handful of industry standards that primarily focused on a single type of structure. Notably, the AWWA D110 and D115 standards existed for , but they did not cover the broader range of structures encountered in practice. Furthermore, general building codes like the IBC, UBC, and ASCE-7 either largely refrained from covering these structures or only provided simplified equations for calculating base shear forces, which proved insufficient for detailed design.
